This invention relates torivet setting machines and has for its object to increase the field of work to which such machines are adapted and also to increase the facility of operation for such machines especially with large work.

Rivet feeding and setting machines have been found through considerable investigation to be desirable in the construction of a variety of articles. Efforts have been and are being made to increase the field of utility for these machines. Heretofore large hollow and cumbersome articles were not readily adapted for construction by such machines except in the early stages and before those articles were formed. With this invention these disadvantages are overcome.

According to this invention the usual rivet setting mechanism is provided but the anvil support is constructed to provide greater clearance below the anvil and toward the rivet setting mechanism support, said clearance also extending below the anvil on at least three sides thereof.

Referring to the drawings, Fig. 1 is a front elevation of one embodiment of this invention.

Fig. 2 is a section on the line 1-1 in Fig. 1, showing a top plan view of the base.

Fig. 3 is an elevation of a slightly modified construction.

Fig. 4 is a section on the line 1-4 in Fig. 3, showing the top plan view of the modified base construction.

As shown in Fig. 1 the base 10 supports the usual standard 11 surmounted by the customary head 12 to which is attached an ordinary rivet feeding mechanism 13 and rivet setting mechanism 14. The customary anvil 15 is provided for cooperation withsaid rivet setting mechanism 14.

7 An extension 16 is provided on the base 10 and has finished vertical surfaces to which the anvil supporting standard 17 is secured by bolts 18 or otherwise as desired. The standard 17 is illustrated in Fig. 1 as diverging upwardly away from the standard 11 so as to increase the clearance below the anvil 15 and between the two standards 11 and 17 A laterally extending arm 19 supports the anvil 15 wardly away from from the upper portion of the standard 17, said arm being secured to the standard by means of' bolts 20 as shown in Fig. 1 or by other suitable securing means. Thestandard 17 is preferably a casting while the arm 19 should be of steel to avoid fracture and provide the requisite strength for rigidly supporting the anvil. The dotted lines in Fig. 2 show the position of the arm 19 and its direction.

The machine illustrated in Figs. 1 and 2 is adapted .for work upon large articles like bags, suitcases, trunks, barrels, large contain ers of various shapes which could not be conveniently handled by prior rivet setting machines. While the machine illustrated is provided with a stationary anvil the clearance may be similarly made large with other types of rivet setting machines, example those having reciprocating or rotary anvils designed for particular purposes.

if desired, as for This machine is adapted for use with various types of rivets and it will be understood thatthe anvil may be shaped to accord with the particular type of rivet used, for example, whether slit or solid or tubular. The usual actuating treadle 21 for the rivet setting mechanism is located sufliciently low and close to the base as not to interfere with the desired clearance below the anvil 15, nor is the usual spring 22 for returning the treadle 21 in the way as it is located quite close to the standard 11.

In- Fig. 3 is shown the same type rivet feeding' and setting mechanism with the usual supporting means therefor including the base 10,'standard 11 and head 12, the customary actuating treadle and spring being removed. As shown in Fig. 4 an extension 23 on the base 10 projects to the operators left side and slightly to the rear. A somewhat similar standard 2 1 diverges upwardly and rearstandard 11 and carries the arm 25 for supporting the anvil 15. Having the arm 25 extending forwardly as shown in Fig. 4, as well as laterally, provides greater clearance at the front of the machine, when such is desired.

Claims:

' 1. The combination with a rivet setting mechanism, of an anvil for cooperation therewith, a standard supporting said mechanism, another standard on one side of the first standard with respect to the operators position and spaced substantially away from the first standard to provide clearance for large and deep workpieces, and a substantially horizontal arm extending from and supporting said anvil from said second mentioned standard, said second standard having its upper portion inclined away from said first standard. I i

2. The combination with a rivet setting mechanism, of an anvil for cooperation therewith, a standard supporting said mechanism, another standard on one side of the first standard with respect to the operators position and spaced substantially away from the first standard to provide clearance for 5 large and deep workpieces, and a substantially horizontal arm extending from and supporting said anvil from said second mentioned standard, said second mentioned standard being located closer to the operators po- ,sition than the first mentioned standard,

said second standard having its upper portion inclined away from said first standard.

3. In a rivet setting machine, the combination with a base, of a standard thereon, a

; head member surmounting said standard,

rivet feeding and setting mechanism secured to said head member, an anvil for cooperation with said rivet setting mechanism, means for supporting said anvil from said base in a manner to provide clearance between said anvil and standard throughout the major portion of the length of said standard below said anvil, and means to actuate said rivet feeding and setting mechanism, said anvil supporting means comprising a lateral extension on said base, a second standard secured to said extension and diverging upwardly away from said first mentioned standard, and a laterally extending substantially horizontal arm supporting said anvil from the upper portion of said second mentioned standard.

4:- In a riveting machine, a base, a first column rising substantially vertically therefrom, rivet setting mechanism on the column,

a second column rising generally vertically from the base and spaced substantially from the first column, a substantially horizontal anvil supporting extension from the top of the second column and having its clear end located below the rivet setting mechanism, and an anvil on said clear end of said anvil extension to cooperate with the rivet setting mechanism, whereby ample clearance for large pieces of work is provided between the columns and below said anvil extension, said second column having its upper portion inclined away from said first column.

' 5. In a riveting machine, a floor base having a lat ,ral extension, a first column rising substantially vertically from the base, rivet setting mechanism on the column, a second-
